HaloMods "Classic" Read-only Archive

i know how to post pictures.(put it under attachments) but i cant put on attachments, you know at the bottom of ur screen how it says like:
you can post new topics
you can reply to topics
bla bla bla
it says for me
you cannot add attachments
i know this is probably a nooby question, but i used search and it didnt help.

go the intro & sigs section, it has a sticky telling you how to use sigs. Just do the same thing, only use the pic you want and post it in your message
